BY THE IMPACT OF RUST ON THE BEARING CAPACITY OF TRUSSED RAFTERS TYPE “MOLODECHNO”

Abstract

In the article the influence of the dependence of the degree of surface corrosion on the bearing capacity of the most loaded rods metal truss made of profiles such as “Molodechno”. The study plotted strength, flexibility-sti and local stability of the wall on the degree of corrosion damage in truss belts surfactant corrosion. It is concluded that the intensity of the exhaustion of the bearing capacity of the elements of the truss, depending on the speed of propagation of corrosion processes.
